Abstract

Advancing EV Research: Novel Technique for EV's Surfaceome Profiling.

The extracellular vesicle (EV) surfaceome plays a crucial role in vesicle targeting, uptake, and functional interactions. However, its characterization remains challenging due to EV heterogeneity and small size, limiting conventional proteomics approaches. In this study, we employed a chemoproteomic approach originally designed for the identification of cell surface proteins in living cells, and adapted it for the untargeted profiling of EV surfaceome. This methodology uses selective enrichment of N-, C-, and Oglycosylated proteins, which are ubiquitously present on the plasma membrane of living cells and, by extension, on the EV surface.
